If you were made of rubber then you would just stretch in response. but humans are composed of other materials such as bones and muscles and organs. your body would stay whole until the instant the tidal force exceeded your body’s molecular bonds. (if the inquisition had access to black holes, this, instead of the rack, would surely have become the stretching device of choice.) which sentence from the excerpt supports the idea that falling into a black hole would be a violent death?

The statement that our body will stay whole only until the molecular forces in the body exceed the tidal forces.

Explanation:

If we are subjected to the intense force such as that generated by a black hole the gravitational forces that will act on the molecules of our body will be highly in excess than the inter molecular forces of attraction that acts between the molecules thus we will be shredded into atoms at  the instant we are subjected to such large forces resulting in a very violent death.

it would be kevlar ^^
